Ciao a questa community!
Sono qui per descrivere un problema che ho riscontrato quando ho cambiato la mia scheda madre.
All'inizio, ho acquistato una scheda madre EVGA Z370 FTW e il mio sistema era ok: a bordo ho installato un Intel i7-8700K con 4x8Gb DDR4 3200Mhz c16 Corsair Vengeance Red Led (codice: CMU32GX4M4C3200C16R).
Con FTW bios versione 1.09 (più recente), tutto ha funzionato al primo avvio.
Ho impostato il profilo XMP1 e la RAM è stata riconosciuta senza problemi su tutti e 4 gli slot. Ho fatto anche un overclock leggero di CPU a 5GHz, senza problemi.
Per far fronte a una limitazione della gestione delle porte PCI / SATA, ho programmato di cambiare la mia FTW con una Z370 Classified K, pensando che fosse la migliore ...
... il risultato è che il mio ram set non è pienamente riconosciuto.
La scheda madre K classificata con versione 1.08 (più recente) del BIOS e tutti gli slot RAM popolati non vengono pubblicati.
Codice postale "C". Ho controllato tutto, ma l'unica soluzione è disinserire 2 moduli RAM.
Ho provato tutti i moduli e gli slot uno per uno. Tutto funziona bene.
Ho provato a cancellare i cmos, a commutare bios e impostare XMP1 su solo 2x moduli e dopo installare gli altri due moduli, ma non viene modificato nulla.
La scheda madre si avvia solo quando sono installati 2x moduli in ogni slot (1-3, 2-4, 1-4, 2-3) e XMP1 funziona correttamente, ma se aggiungo anche un altro modulo, non si avvia e viene visualizzato "C" sul display post.
La cosa strana è che FTW era completamente compatibile con il mio set ... Classified K non lo è.
La mia ram set non è su QVL di entrambe le schede madri.
 
Grazie a tutti

    Sorry to hear that. Guess you'll be sticking with the FTW?

    Post Code "C"
    Are your EPS 8-Pin Connectors Locked into place on the Motherboard as well as the Power Supply Side?
    Using One or Both of the EPS Connectors the 8-Pin & 4-Pin Connectors that is?

    I'll stay with Classified K, because I need sata ports... On FTW, with two m.2 ssd installed, I lose 4 sata ports on 6.
    This was the reason of change.
    Now I'll change my ram on Amazon... my pc is new, so all parts are 2-3 weeks old.
    I chose a set of G.Skill 3200MHz 4x8Gb c16 RGB (pn: F4-3200C16Q-32GTZR), but approved into Vendor List of Classified K on both two and four dimm configurations, paying a difference of only 30 euro (the truth is that I already spent a lot of money for this machine and I'm tired to change parts and pay).
    I hope the QVL will match the reality.

    I'll update you tomorrow...

    My friend,
    I read the manual and check all cables. I installed all power connectors required by motherboard, also the optional EPS 4-pin, from beginning.
    The motherboard is working with set XMP profile on RAM too, but not with 3 or 4 ram dimms. This is the fact.
    FTW recognizes better my (now old) Corsair set of ram.

    UPDATE:
     
    Today I received the new ram F4-3200C16Q-32GTZR...
    At the first boot, when I installed all 4 dimms, post code was "C"... again!
    So I tried to unmount one dimm of set and pc booted.
    After this I mounted again it and pc booted correctly with 4 modules.





    Great!

    Thank you mate!
    The fastest way, in my case, was change the set of ram.
     
    The problem now is relative to RGB management...
    The old set of Corsair wasn't RGB, so I hadn't problem, but with this set of G.Skill is different.
    G.Skill offers a software based on AURA for the RGB management, but it isn't friendly with our EVGA LED SYNC.
    If I don't install its AURA software, the rams run into a random rainbow loop, not synchronized with motherboard and aio led... but if I don't uninstall the AURA software, I cannot apply special effects to the motherboard. Only AIO led individually works and I don't know how it is possible.
    EVGA LED SYNC has a "DIMM" expected field, but I don't know with what RAM brand it should work at this point.
    Does EVGA have a partnership with some RAM manufacturers???
    So the only way I have is this:
    Set the static led color for Motherboard and AIO into EVGA LED SYNC and close it (it doesn't have to run in background), install and use AURA for setup the RGB on ram.
    When I need to change led color for Motherboard and AIO, I can launch again the EVGA LED SYNC, change it and close it again.
     
    Do you have any suggestions about this?
     
    Thank you
